am not a professional mountaineering guide, but I can provide some basic information for reference. However, please be aware that high-altitude mountaineering itself is very risky, especially when not carrying supplemental oxygen, and any advice must be practiced with professional training, adequate preparation, and the accompaniment of a professional guide and medical team. The following are some aspects that need to be considered in general, but remember that they cannot replace professional advice: 1. Adequate acclimatization: • The most important step is to gradually adapt your body to the low oxygen environment. Many successful high-altitude climbers will adopt the strategy of "climbing high and sleeping low", arranging multiple phases of acclimatization camps to help the body adapt to the high-altitude hypoxic environment through gradual ascent and rest. • You can acclimate your body to the low oxygen content of the air in advance through altitude training (such as training in a high-altitude environment or using altitude simulation equipment) before climbing. 2. Strict physical and health preparation: • Carry out systematic aerobic training, strength training, and endurance training to enhance cardiopulmonary function, improve blood circulation, and overall physical fitness. • Get a comprehensive medical examination and discuss your personal condition and plan with a mountaineering medicine expert. Acute mountain sickness (AMS), high altitude cerebral edema (HACE) or high altitude pulmonary edema (HAPE) may occur under high altitude conditions. You must be aware of their signs and have emergency measures. 3. Careful itinerary planning and gradual advancement: • Make a reasonable climbing plan, control the altitude increase each day, and reserve sufficient time for rest and adaptation. • Arrange sufficient flexibility to retreat or terminate the plan so that you can descend to a lower altitude in time if you feel unwell. 4. Equipment and logistics support: • In addition to basic mountaineering equipment, it is very important to prepare medical equipment for high altitude environments (such as oxygen emergency equipment, high altitude-suitable medicines). Even if it is not used as a regular oxygen supplement, it can play a role in an emergency. • Equipped with reliable communication equipment to ensure that you can call for help and obtain external support in time in an emergency. 5. Support from professional teams and guides: • Cooperate with mountaineering guides and teams with rich high altitude experience, who have extensive knowledge of the local environment, weather changes and emergency rescue measures. • During the climbing process, strictly follow the advice of the guide and team and do not take risks easily. 6. Mental preparation and flexibility: • High-altitude mountaineering is full of uncertainty. You must stay calm and flexible. Do not ignore the warning signals from your body because of high expectations. • If you feel serious discomfort, you should be determined to stop climbing and retreat in time. Once again, the above are only some basic references and cannot replace the practical guidance of professional training, detailed planning and professional teams. Before climbing, please be sure to consult professional mountaineering coaches and medical experts, carefully assess the risks, and make adequate emergency plans. Safety first, it is not recommended to try high-altitude anaerobic mountaineering without adequate preparation.
